Dichloro-(2-chloroethoxy)-phosphine, also known as 2,2-dichlorovinyl dimethyl phosphate or DCP, is a colorless, oily liquid with a pungent odor. It is an organophosphorus compound that is used as a chemical warfare agent, specifically as a nerve agent. DCP is highly toxic and can cause severe health effects, including respiratory failure, paralysis, and death. It is a colorless liquid with a pungent odor and is soluble in organic solvents. The compound is produced by the reaction of phosphorus trichloride with 2-chloroethanol. Due to its high toxicity and potential for misuse, the production and stockpiling of DCP are regulated under international chemical weapons conventions.

Check Digit Verification of cas no

The CAS Registry Mumber 7623-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,2 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7623-05:
(6*7)+(5*6)+(4*2)+(3*3)+(2*0)+(1*5)=94
94 % 10 = 4
So 7623-05-4 is a valid CAS Registry Number.
